[mrtg] Problem with mrtg and snmpd on FreeBSD

[Moriarty]

Hi,

I recently compiled a new kernel for FreeBSD 4.7 stable and ever since i
havent been able to get it working. It generates the stats for xl0
(10.4.3.10) (3com 905c nic) perfectly, which is first in the config, but the
mrtg process breaks with the below error message when trying to make the
stats for the wireless device wi0 (10.4.1.20) (Avaya 802.11b nic). I had
this setup running fine until an unrelated program needed changes to the
kernel. Anyhow, heres the error generated when i run mrtg..

<Start of error>

[/] # /usr/local/bin/mrtg /usr/local/etc/mrtg/mrtg.cfg

<End of error>

The config file has not been changed since it was working. Any other info
required that could be of help in figuring out this problem is also
available, but i dont want to paste out a lot of stuff that may be totally
irrelevant.

Any help on how to get mrtg going again greatly appreciated..

Moriarty
